Abstract: PURPOSE:To provide a surface emission threshold laser having a high emission efficiency in a specific wavelength band by a method wherein specific nonferrous metals are contained in the quantum wells of an active layer and a saturable absorption layer respectively. CONSTITUTION:A band gap EgB4 of an Sb-containing distorted quantum well B4 is smaller than that EgB2 of an In-containing strained quantum well B2, and an electron quantum level 15 of the strained quantum well B4 is higher in terms of energy than that 16 of the strained quantum well B2, and on the other hand, a hole quantum level 17 of the strained quantum well B4 is set lower in terms of energy than that 18 of the strained quantum well B2. The band gap EgA4 of a quantum well A4 of an active layer which oscillates laser rays of wavelength 0.98mum is nearly equal to the band gap EgB4 of the strained quantum well B4 of a saturable absorption layer but smaller than the band gap EgB2 of the strained quantum well B2. By this setup, a surface emission laser of this constitution can be exhibit a high emission efficiency in a wavelength band of 0.98mum.
